If you let us at Day1Wake know what price range you are in, we would be happy to try to make you one. We build custom wakesurf boards and our "XANI" is probably exactly what you are looking for in a "longer board", (it is a 5'2 swallow and rides great for anyone up to about 250lbs).

If you really just want an off the shelf model at a decent price, try Evo.com. They have an "Outlet" section to their site. I have purchased from them many times - they are highly reliable. Of course, I would still recommend giving us a shot, though
